SYSTEM, METHOD AND RECORDING MEDIUM FOR ANALOG TO DIGITAL CONVERTER CALIBRATION

摘要

PROBLEM TO BE SOLVED: To provide a calibration system for an analog-to-digital converter (ADC) internal ADC that receives an analog input and converts an analog input to digital multi-bit data.SOLUTION: The calibration system includes a noise source, and a reference shuffling circuit that shuffles reference values of comparators of the internal ADC. The calibration system also includes a calibration circuit that calibrates the comparators of the internal ADC. The calibration system also includes a digital block that measures amplitude based on the digital multi-bit data. The calibration system also includes calibration logic that controls the calibration circuit based on an output of the digital block.
